BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to an image display device and a program.

2. Description of the Related Art

An image display device in which two images are superimposed on eachother using a half mirror is proposed (see, for example, JapaneseUnexamined Patent Application Publication (JP-A) No. 8-122695). FIG. 4of JP-A No. 8-122695 illustrates an image device with which a viewer mayview a synthesized image obtained by superimposing a background imagebehind a half mirror and passing through the half mirror and an imagereflected on the half mirror on each other.

The half mirror used in the image device of JP-A No. 8-122695 isproduced by depositing a metal reflective layer such as a chromium orSUS layer as thin as possible, almost translucent, at least on one sideof a glass material. Therefore, the half mirror is relatively expensive.

The half mirror described in JP-A No. 8-122695 has reflectance of 50%and transmittance of 50%. Although these numerical values are examples,transmittance of the background image is typically low in the halfmirror because of the existence of the metal reflective layer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a schematic perspective view of a packaging containeraccording to an embodiment of the present invention. As illustrated inFIG. 1, a packaging container 1 includes a box body 10, a stereoscopicobject 20, a transparent plate (i.e., a clear card) 30, and a lid body40. In the box body 10, goods or articles (not illustrated), such ascandies and toys, may be contained together with the stereoscopic object20 and the transparent plate 30, and the box body 10 is covered by thelid body 40 from above. Thus, the box body 10 may be used as thepackaging container 1 for various goods.

The box body 10 includes a bottom wall 11 on which the stereoscopicobject 20 is placed, a rear wall 12 disposed behind the stereoscopicobject 20, and side walls 13 and 13 extending forward from the rear wall12 at both sides of the stereoscopic object 20. The box body 10 has anupper opening 15 which faces the bottom wall 11, and a front opening 16which faces the rear wall 12. In a case in which the packaging container1 is not configured, the bottom wall 11 and the rear wall 12 areunnecessary. In the present embodiment, the box body 10 further includesa front wall 14 which faces the rear wall 12. The front wall 14 includestwo side edge walls 14A and 14B disposed at both sides of the frontopening 16 to define an opening width of the front opening 16. The frontwall 14 may further include a lower edge wall 14C which stands up fromthe bottom wall 11 to define a lower end of the front opening 16.

A height L1 of the box body 10 is lower than a length L2 of thetransparent plate 30 (L1<L2). A height L3 of the lid body 40 is higherthan a length L2 of the transparent plate 30 (L1<L2<L3). With thisconfiguration, the transparent plate 30 may be leaned inside the boxbody 10 and the box body 10 may be covered by the lid body 40 fromabove. The lid body 40 has, for example, a shape of a lid box body withits lower end open. The lid body 40 includes folding pieces 41 and 41which are folded and made to adhere to the bottom wall 11 of the boxbody 10 using an adhesive tape or the like, whereby the lid body 40 ismounted on and fixed to the box body 10.

The stereoscopic object 20 includes projections and recesses on thefront thereof as illustrated in FIG. 2. The example illustrated in FIG.2 is a stereoscopic object of a building. The stereoscopic object 20 isnot limited to a building but may be various characters and figures. Thestereoscopic object 20 may be made of resin or metal, or may be a papercraft. The stereoscopic object 20 may be fixed to the rear wall 12 ofthe box body 10. Alternatively, the stereoscopic object 20 may be takenout of the packaging container 1 and disposed back to back on the rearwall 12. Although the stereoscopic object 20 is used in the presentembodiment, non-stereoscopic objects, such as a card and a wall on whicha background is drawn, may also be used. The object may be replaceable.Further, the object and the rear wall 12 may be removed so that actualscenery and an actual building may be viewed through the transparentplate 30. In that case, the image display displayed on the transparentplate 30 may be viewed in a superimposed manner on the actual sceneryand the actual building which are viewed through the transparent plate30.

The transparent plate 30 is formed as a thin plate by a materialtransparent (i.e., having transparency) to the wavelength bands ofvisible light, such as glass or resin. The transparent plate 30 isdesirably formed by compact of resin, such as polyvinyl chloride (PVC),polyethylene terephthalate (PET), polycarbonate (PC), or acrylic resin,from the standpoint of difficulty in damaging and reduction in weight.Polyethylene terephthalate is desirable from the standpoint of a lowproduction cost. Regarding thickness of the transparent plate 30, equalto or thicker than 0.4 mm is desirable from the standpoint of intensity.The thickness of the transparent plate 30 is desirably equal to or lowerthan 0.6 mm as a surface on which an image is reflected and on which animage is displayed. As illustrated in FIG. 3, the transparent plate 30is disposed between the side walls 13 and 13 of the box body 10 and infront of the stereoscopic object 20 such that a lower end portion 32 issituated in front of an upper end portion 31 (for example, angle ofinclination=45 degrees). That is, the transparent plate 30 is situatedfurther toward a user than the stereoscopic object 20.

A placement section 21 on which the upper end portion 31 of thetransparent plate 30 may be placed is formed on an upper surface of thestereoscopic object 20. The placement section 21 is formed as, forexample, an inclined surface inclined downward toward the front. Byproviding such placement section 21, an angle of the transparent plate30 is defined such that an image on a display section 110 (see FIG. 5)is superimposed at a surface position of the stereoscopic object 20viewed through the transparent plate 30, thereby providing a clearerimage to a user. In this embodiment, the inclined surface inclineddownward toward the front is used as the placement section. However, theposition and shape of the placement section are not limited to such aninclined surface as long as positioning in which the image of thedisplay section 110 is superimposed at a surface position of thestereoscopic object 20 viewed through the transparent plate 30 isachieved. For example, a placement section which may fix the upper endportion 31 of the transparent plate 30 may be provided at a front sideof the stereoscopic object 20, or a placement section may be provided inthe box body. Further, as illustrated in FIGS. 2 and 3, two sidestoppers 22 and 22 projecting upward at both ends in the width directionof the placement section 21 may be provided on the upper surface of thestereoscopic object 20. These two side stoppers 22 and 22 may positionthe transparent plate 30 in the width direction. The side stoppers maybe provided in the box body. The lower end portion 32 of the transparentplate 30 is locked at a corner at which the bottom wall 11 and the frontwall 14 (14A to 14C) of the box body 10 cross each other as illustratedin FIG. 3.

FIGS. 3 and 5 illustrate a usage condition of an image display device inwhich a portable terminal (for example, a smartphone) 100 provided withthe display section 110 illustrated in FIG. 6 is placed on top of theside walls 13 and 13 of the box body 10 with the display section 110facing below (i.e., the portable terminal 100 is supported from the sideof the display section 110). The image display device is configured byassembling among the members illustrated in FIG. 1 the box body 10, thestereoscopic object 20, and the transparent plate 30, excluding the lidbody 40, as illustrated in FIGS. 3 and 5. FIG. 7 illustrates an exampleof image display viewed from the front opening 16 in the usage conditionof the image display device illustrated in FIGS. 3 and 5. As illustratedin FIG. 7, the transparent plate 30 is visible from the front opening16. In the present embodiment, the portable terminal is supported by thebox body and may be supported by at least two wall surface portionsamong the side walls 13 and 13, the rear wall 12, and the front wall 14.That is, in the present embodiment, at least two wall surfacessupporting the portable terminal 100, i.e., at least two wall surfacesamong the side walls 13 and 13, the rear wall 12, and the front wall 14serve also as a “support section” of the present invention. However, thewall surfaces of the box body do not necessarily serve also as the“support section” and the “support section” of the present invention maybe provided separately. It is sufficient that the “support section”which may support the portable terminal 100 from the side of the displaysection 110 is provided. It is further desirable that, with the supportsection, the transparent plate 30 is situated below the display section110 of the portable terminal 100.

The right and left side walls 13 sandwich the transparent plate 30 sothat an upper side space at an upper side of the transparent plate 30and a rear side space at a rear side of the transparent plate 30 aredefined. The stereoscopic object 20 is positioned in the rear sidespace. The upper side space has a brightness different from a brightnessof the rear side space. Specifically, the upper side space is brighterthan the rear side space.

In the image display device according to the present embodiment, asillustrated in FIG. 3, an image Im2 of the display section 110 of theportable terminal 100 reflected on the transparent plate 30 issuperimposed on a perspective stereoscopic image Im1 of the stereoscopicobject 20 entering from behind the transparent plate 30 and viewedthrough the transparent plate 30. At this time, since the side behindthe transparent plate 30 at which the stereoscopic object 20 is disposedis surrounded by the stereoscopic object 20, the side walls 13 and 13,and the portable terminal 100, the side behind the transparent plate 30is darker than the side of the front opening 16 in front of thetransparent plate 30. For a viewer who directly views the stereoscopicobject 20 (i.e., the dark side) from the front opening 16 side in frontof the transparent plate 30 (i.e., from the light side), thestereoscopic object 20 may be viewed through the transparent plate 30and, at the same time, the viewer may also view the image Im2 of thedisplay section 110 of the portable terminal 100 that is reflected onthe transparent plate 30 (i.e., displayed on the transparent plate 30).That is, the image display device of the present embodiment includeslight and dark difference generating means (in the present embodiment,any one of or a combination of the stereoscopic object 20, the sidewalls 13 and 13, the bottom wall 11, the front wall 14, the rear wall12, and the portable terminal 100) which may produce via the transparentplate 30 a difference in light and dark between one space (i.e., a spacein which the user exists with respect to the transparent plate 30: infront of the transparent plate 30 in the present embodiment) and theother space (i.e., a space on the opposite side of the user with respectto the transparent plate 30: behind the transparent plate 30 in thepresent embodiment). Accordingly, the user may view the side behind thetransparent plate 30 (i.e., the space on the opposite side of the userwith respect to the transparent plate 30) through the transparent plate30 and, at the same time, the user may view the image Im2 of the displaysection 110 of the portable terminal 100 reflected on the transparentplate 30 (i.e., displayed on the transparent plate 30). This phenomenonon the transparent plate 30 is the same as a phenomenon on a car windowat night on which an occupant's face is superimposed on a scene viewedthrough the car window. Since the transparent plate 30 is disposed in aninclined manner, the transparent plate 30 may reflect and display theimage of the display section 110 to the viewer. Thus, according to theimage display device of the present embodiment, the image of the displaysection 110 reflected on the transparent plate 30 may be superimposed onthe stereoscopic object 20 viewed through the transparent plate 30 withrelatively high transmittance without using a half mirror.

As illustrated in FIG. 4 which is an enlarged view of section IV of FIG.3, the transparent plate 30 may be formed by laminating a plurality oftransparent thin plates 30A to 30C. With this configuration, each ofinterfaces between the plurality of transparent thin plates 30A, 30B,and 30C functions as a reflecting layer and thus reflectance may beincreased. Since the transmittance decreases as a result of increasedreflectance, the space behind the transparent plate 30 becomes darkerand the effect of the above phenomenon via the transparent plate 30 isincreased. A reflected image 122 obtained by reflecting an image 120 ofthe display section 110 on two transparent thin plates 30A and 30B asillustrated in FIG. 8B is clearer than a reflected image 121 obtained byreflecting an image 120 of the display section 110 on a singletransparent thin plate 30A as illustrated in FIG. 8A.

Here, a thickness of each of the transparent thin plates 30A to 30C maybe equal to or smaller than 0.45 mm. If each of the transparent thinplates 30A to 30C is thicker than 0.45 mm, position misalignment iscaused between the reflected images on different interfaces asillustrated in FIG. 4, and blur in a composite reflected image becomesnoticeable. If the transparent plate 30 is made of resin, whenformability is considered, the thickness of each of the transparent thinplates 30A to 30C may be 0.15 mm to 0.45 mm.

The number of transparent thin plates to be laminated is desirably twoto four when the thickness mentioned above is considered; If the numberof transparent thin plates to be laminated is greater than four,position misalignment is caused between the reflected images ondifferent interfaces, and blur in a composite reflected image becomesnoticeable.

The transparent plate 30 or the plurality of transparent thin plates 30Ato 30C may be colored gray or the like. By coloring the transparentplate 30 or the plurality of transparent thin plates 30A to 30C,transmittance of the transparent plate 30 or the plurality oftransparent thin plates 30A to 30C may be lowered; and by making thespace behind the transparent plate 30 or the plurality of transparentthin plates 30A to 30C darker, reflectance on the transparent plate 30may be increased.

The plurality of transparent thin plates 30A to 30C may be fixed in alaminated state to increase handleability. The plurality of transparentthin plates 30A to 30C may be fixed by welding (including ultrasonicwelding), adhering, pressure bonding, or fixing with a frame.

The image displayed on the display section 110 of the portable terminal100 illustrated in FIG. 6 may be a still image or may be a moving image.For example, on the display section 110, a moving image 120B of whichdisplay position, shape, color, and the like change with time isdisplayed as projection mapping on the background stereoscopic object 20together with a still image 120A of the same color and outline as thoseof a front image of the stereoscopic object 20. In this manner, bysuperimposing the still image of the stereoscopic object viewed throughthe transparent plate 30 on the image of the display section 110including the moving image, variously created pseudo images, such as 3Dhologram, (for example, an image in which the stereoscopic object ismoving) may be reproduced at the front opening 16 of the image displaydevice illustrated in FIG. 7. That is, the stereoscopic object 20includes a plurality of items (such as windows, a door and so on), andthe image 120 includes a plurality of image pieces including the stillimage 120A and the moving image 120B. As shown in FIG. 6, at least oneof the plurality of items in the stereoscopic object 20 (a part of afrontal view of the objet 20 corresponding to one of the items in theobject 20) and one of the plurality of image pieces have the sameoutline in shape, and can be seen as overlapping each other on thetransparent plate 30.

As illustrated in FIG. 7, a viewing angle at the front opening 16 of theimage display device is limited by the side edge walls 14A and 14B.Therefore, even if the display section 110 of the portable terminal 100is a liquid crystal display section or the like, the viewing angle atthe front opening 16 of the display device may be adapted to a viewingangle of the liquid crystal display section. Since the field of view atthe front opening 16 of the image display device is limited by the sideedge walls 14A and 14B and the lower edge wall 14C, unnecessarybackgrounds of the bottom wall 11, side walls 13 and 13, and the like ofthe box body 10 may be hidden.

In the present embodiment, since the portable terminal 100 is supportedfrom the display section 110 side, the transparent plate 30 is situatedbelow the display section 110 of the supported portable terminal 100.Then, unless the user lifts the image display device above the eye lineand tries to view inside the front opening 16 from below (viewing frombelow is not a normal usage situation because the space behind thetransparent plate 30 (i.e., the rear side: the space on the oppositeside of the user with respect to the transparent plate 30) is not easilyviewed from the front opening 16), the display on the display section110 of the portable terminal 100 is not easily viewed by the user.Therefore, a situation in which the user views both the image display onthe transparent plate 30 and the display section 110 of the portableterminal 100 and loses interest may be reduced.

In order to superimpose the image of the display section 110 of theportable terminal 100 on the stereoscopic object 20 and to align theportable terminal 100 with the box body 10, a marker may be provided inthe box body 10, the stereoscopic object 20, or the display section 110.A marker 23 is provided at, for example, the center in the widthdirection on the upper surface of the stereoscopic object 20 in FIGS. 1to 3. A centerline of the display section 110 of the portable terminal100 may be aligned with the marker 23.

FIG. 9 illustrates markers 130 to 133 displayed on the display section110 of the portable terminal 100. The marker 130 may be displayed at aposition corresponding to the marker 23 provided in the stereoscopicobject 20. The marker 131 is aligned with the side walls 13 and 13 ofthe box body 10. The marker 132 is aligned with the rear wall 12 of thebox body 10. The marker 133 is aligned with the side edge walls 14A and14B of the box body 10. The display section 110 may display one or moreof markers 130 to 133.

As illustrated in FIG. 10, a base station 210 which communicates withthe portable terminal 100 is connected to a server 220 via a network200. As illustrated in FIG. 11, the portable terminal 100 includes anacquisition section 150 connected to a camera 140 illustrated in FIG. 9other than the display section 110. The camera 140 of the portableterminal 100 reads QR code (registered trademark) 17 which is a 2D codeprovided in the box body 10 as illustrated in FIG. 1, and the read codeinformation is acquired by the acquisition section 150. The portableterminal 100 further includes an input section 160 for inputting an iconor the like to be displayed on the display section 110, and acommunication section 170. The communication section 170 communicateswith the server 220 using a URL included in the QR code (registeredtrademark) 17, which is access information of the server 220. The server220 includes a communication section 221 and a storage section 222 asillustrated in FIG. 12. The server 220 executes the following Procedures1 and 2 in accordance with a program stored in the storage section 222to the portable terminal 100 accessed on the basis of the QR code(registered trademark) 17. As Procedure 1, the server 220 reads data ofan image of at least one marker among the markers 130 to 133 illustratedin FIG. 9 from the storage section 222 and transmits the data to theportable terminal 100 via the communication section 221, the network200, and the base station 210. As Procedure 2, the server 220 reads dataof the images 120A and 120B illustrated in FIG. 6 from the storagesection 222 and transmits the data to the portable terminal 100 via thecommunication section 221, the network 200, and the base station 210.

The server 220 may let the image of the marker of Procedure 1 bedisplayed on the display section 110 of the portable terminal 100 for apredetermined initial time and then proceed to Procedure 2. That is,after the portable terminal 100 is aligned using the markers 130 to 133displayed by Procedure 1, the markers 130 to 133 are not displayed.Alternatively, the server 220 may let the image of the marker ofProcedure 1 be displayed on the display section 110 of the portableterminal 100 for a predetermined initial time and then executeProcedures 1 and 2 in parallel. That is, the image of the marker may bedisplayed as an initial image, or continuously displayed with the images120A and 120B illustrated in FIG. 6.

The form of the present invention is not limited to the embodimentdescribed above and components may be added, excluded, or modifiedsuitably.

For example, the box body 10 and the lid body 40 are not necessarilyprovided separately as illustrated in FIG. 1. A box body 10A illustratedin FIG. 13 may integrally include a first lid body 42 which covers anupper opening 15 and a second lid body 43 which covers a front opening16. The first lid body 42 and the second lid body 43 are connected tothe box body 10A via, for example, perforation lines and are separatedfrom the box body 10A at the time of use.

As illustrated in FIG. 14, since the box body 10A has a height L3 thatis the same as the height L3 of the lid body 40 illustrated in FIG. 1,the transparent plate 30 having the length L2 (see FIG. 1) may becontained at a vertical position in the box body 10A. As illustrated inFIG. 14, a placement section for placing the upper end portion 31 of thetransparent plate 30 may also be provided on a rear wall 12A of the boxbody 10A instead of the stereoscopic object 20.

What is claimed is:
 1. An image display device, comprising an object; atransparent plate disposed in an inclined manner and being positionedfarther forward than the object; a supporting member configured tosupport a display device to be capable of projecting an image toward thetransparent plate, thereby overlapping the image with a frontal view ofthe object, the display device having a display that displays the image;and right and left side walls each extending along a corresponding oneof two side surfaces of the transparent plate, the two side surfacesfacing each other, wherein the frontal view of the object includes aplurality of pieces and the image displayed by the display includes aplurality of item images, and at least one of the plurality of piecesand at least one of the plurality of item images have the same outlinein shape, a perspective view of the object that is seen through thetransparent plate overlaps the image reflected by the transparent plate,and the right and left side walls sandwich the transparent plate so thatan upper side space at an upper side of the transparent plate and a rearside space at a rear side of the transparent plate are defined, theobject being positioned in the rear side space, the upper side spacehaving a brightness different from a brightness of the rear side space.
